Abstract:

Redistribution of alloying elements occurs in a vacuum of 10 to the minus seventh power mm Hg at temperatures of 800-1000C as result of the sublimation of the low-volatile compounds and elements on the surface of titanium alloys. This leads to a change in the physicochemical and mechanical properties of the titanium alloys. The qualitative agreement of thermodynamic and microspectral analysis results for redistribution of alloying elements was established. As a result of metallographic investigations of titanium alloys, the fact that sublimation is accompanied by formation of a step relief and emergence of dislocations on the sample surface was established.
